I own a 2009 bmw 335. It was purchased in early 2009. Prior to the failure of the part, there was no sign of trouble. While I was driving on the freeway in southern california, my car started to lose power. Concurrent with that power loss, the "service engine soon" light appeared on my instrument cluster. Additionally, an icon (it looked like a transmission) lit up as well. When the power loss first occurred, I was in the fast lane on the freeway. I had to work extremely quick to get to the other side of the freeway, for fear that someone would hit me from behind (as my car slowed down). I eventually made it to the other side of the freeway without incident. I pulled off to the side of the road and turned the car off. I eventually called a tow truck and had my car towed to the nearest bmw dealership. Turns out that my high-pressure fuel pump failed. I did not have any warning prior to the failure. The dealership replaced the high-pressure fuel pump. Since then, I have put 5500 miles on the car. My fuel pump is still working properly.
